Passing the additional args changes the api that is used for this function call. Also, not be be a downer about the difference in performance, but it isn't a real good practice to optimize in isolated instances, if this idea of passing around arguments (view, StateManager) were an accepted thing to do in the codebase then I could see this difference, but otherwise there is not benefit to it.
